Abstract

Jedan od glavnih indikatora kakvoće vode predstavlja stupanj trofije. Antropogeni procesi poput
intenzivne poljoprivredne i stočarske proizvodnje, prilikom neodgovorne primjene, doprinose
napretku procesa eutrofikacije. Svrha ovoga rada bila je provjeriti utječe li intenzitet biljne i
stočarske proizvodnje na koncentracije nitrata te na kakvoću vode na području Zagrebačke
županije. Uzorkovanje je provedeno na dvije lokacije u dva navrata u vremenskom razdoblju od
dva mjeseca na području općine Pušća te općine Farkaševac. Korištenjem GIS alata izrađene su
karte korištenja zemljišta te se pomoću statističkih metoda poput statističke analize varijance
(ANOVA) utvrdilo prihvaća li se ili odbacuje početno postavljena hipoteza. Na temelju dobivenih
rezultata utvrđeno je kako dominantan utjecaj na kakvoću voda nema poljoprivreda već su
povećane koncentracije nitrata posljedica nagle urbanizacije, različitog reljefa, utjecaja
zagrebačkog vodonosnika i sl. U konačnici su iznesene par potencijalnih mjera poboljšanja
trenutnog stanja.

Abstract (english)

One of the main indicators of water quality is the trophy level. Anthropogenic processes such as
intensive agricultural and livestock production, when applied irresponsibly, contribute to the
progress of the eutrophication process. The purpose of this work was to check the impact of crop
and livestock production on nitrate concentrations and water quality in the area of Zagreb
County. Sampling was carried out at two locations on two occasions in a period of two months in
the area of Pušća and Farkaševac municipalities. Using GIS tools, land use maps were created and
statistical methods such as statistical analysis of variance (ANOVA) were used to determine
whether the initial hypothesis was accepted or rejected. Based on the obtained results, it was
determined that agriculture does not have a dominant influence on water quality, but that nitrate
concentrations have increased due to sudden urbanization, different relief, the influence of the
Zagreb aquifer, etc. In the end, a couple of potential measures to improve the current situation
were presented.
